As an alternative, the server-assisted schemes of RSA cryptography called
¡§SARSA¡¨ (Server-assisted RSA algorithm) and ECC cryptography called ¡§SAECC¡¨
(Server-assisted ECC algorithm) are proposed. The schemes provide the basis for
an effective but low-cost solution to the PKI support for wireless clients. The
client, by driving the gateway server to compute the RSA/ECC cryptographic
processing on his/her behalf, can accomplish PKI functions with his/her own
minimal resources. Of course, the gateway is blinded of the computational
parameters to prevent information leakage and to uphold end-to-end security.
A pilot project with a local online wireless storefront called ¡§Wireless PKI
e-shop¡¨ is conducted to demonstrate the feasibility and practicality of the
technology when applied on mobile commerce. The storefront uses not only SARSA/SAECC
utilities but also message digest (e.g. MD5) and secret (symmetric) key
encryption (e.g. DES) so as to illustrate a successful and secure transaction
used in the mobile commerce.
Outcome of the project is expected to benefit all parties, including the network
operators, device manufacturers, solution providers, and online merchants. The
public customers will be the ultimate beneficiaries when the convenience of
e-banking, online shopping and information access becomes real in our daily
life. This project is co-operated with IBM and HKU. ¡@

Server-Assisted Wireless
Public-Key Infrastructure
This project aims at developing a data security technology for enabling
e-commerce on wireless platforms. When bridging a client (mobile device such as
wireless Palm) with an application server, the wireless gateway also exposes a
security loophole of the architecture. An end-to-end security solution is to
enhance the client device with SIM/WIM smart-card to handle the expensive PKI
(Public-Key Infrastructure) operations bypassing the SSL/WTLS exchange at the
gateway.

Automated Data Mining for Hot Bundle Analysis and
Inventory Control
Industry players agree that data mining technology, as one of the strong pillars
in CRM (Customer Relationship Management), plays an important role in
discovering customer behavior. However, applying the technology in business
applications requires mining experts. Without expertise in adjusting more than
20 parameters in the mining process, data mining means nothing valuable to
enterprises. We introduce this R&D project to propose a fundamental change to
traditional data mining tools to minimize the involvement of technical expertise
in adjusting parameters.
The first problem we tackle is the mining of association rule which has found
applications in many different business arenas. We propose to consider a more
practical problem, roughly speaking, it is to mine the top N most frequent
itemsets, new algorithms are introduced for mining N-most interesting itemsets.
Another application of association rule is in the inventory control problem,
where the products carried by a retailer or a service provider are varied from
time to time to optimize the profits. For such a problem the effect of
cross-selling should be considered. We strongly believe the research output
would benefit the Hong Kong-based enterprises by the way of understanding their
customer behavior through automated and manageable data mining platform.

Drill Process Monitoring System ¡V Drill Depth
Calculation
Hong Kong's mountainous terrain, heavy rain and dense development make us to
prone to risk from landslides, which could threaten life and property, block
roads and disrupt the lives of the community. As human cannot eradicate risks
thoroughly, there are ways to reduce them, such as exercising geotechnical
control on investigation, design and construction of new slopes and
systematically investigating and upgrading government slopes. The Geotechnical
Engineering Office (GEO) of the Civil Engineering Department (CED) established
in 1977 not only governs the control but also provides the aesthetics of the
slopes. It supervises abundant of slope safety-related projects rectifying the
substandard slopes, which includes the following major processes:
The ground investigation is carried out by a specialist contractor using
boring and drilling rigs and excavators to take soil and rock samples in order
to check the ground condition and its engineering properties and look for and
identify any industrial contamination.
A soil test is a process by which elements (e.g. phosphorus, potassium,
calcium, magnesium, sodium, sulfur, manganese, copper and zinc) are chemically
removed from the soil and measured for their "plant available" content within
the sample. The quantity of available nutrients in the sample determines the
amount of fertilizer that is recommended. A soil test also measures soil pH,
humic matter and exchangeable acidity. These analyses indicate whether lime is
needed and, if so, how much to apply. Usually, this process is conducted by a
chemist and is used for the landscape treatment of hydro-seeding the slope.
After the previous processes identifying the potential critical surface, with
the aid of computer, a design containing a series of pits to be drilled with
the pit position and the pit depth along the slope is worked out.
The upgrading works and landscape treatment involves the following tasks. The
upgrading works rectifies the slopes for higher safety standards while the
landscape treatment beautifies the slopes for a better environment.

In this project, we are interested in finding the drilling depth and detecting
any barriers (e.g. rock and stone) during drilling process. There are two
major concerns in the traditional drilling project. Whenever excavators
suspect to encounter barriers during drilling, site workers and communities
may make their own decision based on their experience to terminate the
drilling process, because a barrier may indicate a stop of drilling. However,
as the barriers appear behind the slope, nobody knows whether there are
barriers without any further investigation, especially during the drilling
process. For the sake of clarity of the existence, it is a need to carry out
barrier detection during the drilling process. Also, the drilling depth is
measured manually after the drilling process, which is quite costly. Another
drawback is that any fault made during the drilling process cannot be found
(e.g. insufficient depth drilling) until the final measurement is conducted.
It is time-consuming for excavators to re-dig pits with a greater depth. An
early diagnosis of determining the drilling depth and detecting any barriers
can help to improve the situations.
